Hi:
I'm trying to start some processes and connect them using pipes with ABCL (like Unix shell pipes). I've reviewed the documentation but I haven't found anything. Are I missing something? If not, are there any plans of adding input, output and error parameters for run-program (like SBCL, CCL, etc.)?
There's a function like that in run-program.lisp: (defun run-program (program args &key environment (wait t) clear-environment) "Run PROGRAM with ARGS in with ENVIRONMENT variables. Possibly WAIT for subprocess to exit. Optionally CLEAR-ENVIRONMENT of the subprocess of any non specified values. Creates a new process running the the PROGRAM. ARGS are a list of strings to be passed to the program as arguments. For no arguments, use nil which means that just the name of the program is passed as arg 0. Returns a process structure containing the JAVA-OBJECT wrapped Process object, and the PROCESS-INPUT, PROCESS-OUTPUT, and PROCESS-ERROR streams. c.f. http://download.oracle.com/javase/6/docs/api/java/lang/Process.html Notes about Unix environments (as in the :environment): * The ABCL implementation of run-program, like SBCL, Perl and many other programs, copies the Unix environment by default. * Running Unix programs from a setuid process, or in any other situation where the Unix environment is under the control of someone else, is a mother lode of security problems. If you are contemplating doing this, read about it first. (The Perl community has a lot of good documentation about this and other security issues in script-like programs. The &key arguments have the following meanings: :environment An alist of STRINGs (name . value) describing new environment values that replace existing ones. :clear-env If non-NIL, the current environment is cleared before the values supplied by :environment are inserted. :wait If non-NIL, which is the default, wait until the created process finishes. If NIL, continue running Lisp until the program finishes. " Does that solve your problem? -- Bye, Erik. http://efficito.com -- Hosted accounting and ERP. Robust and Flexible.
